A valve is a trunnion ball valve with a disc, which is part of the valve, which controls the flow through them. The ball has a hole, or port, by the way, if the port is in line with the two ends of the valve occurs, the flow rate. When the valve is closed, the hole is blocked perpendicular to the ends of the valve and flow. The handle or lever is in line with the position of the port, you can "see" the valve position.

trunnion ball valve are durable and usually work to get a perfect cut, even after years of stagnation. They are an excellent choice for applications detention (and often the valves and valves for this purpose is preferred.) They do not provide precise control needed in applications that can control, but sometimes used for this purpose.

Ball valves are widely used in industry because they are very versatile, bearing pressure of 700 bar and temperatures up to 200 ° C. sizes typically range from 0.5 cm to 30 cm. They are easy to repair and operate.

The ball generally mark-o-fix is sometimes used at home after leading the United Kingdom.

Types of touch

There are five common body styles of ball valves: single body, in three parts, with the divided body, top entry, and soldiers. especially if the ball contains - - The difference is produced and assembled like the pieces of the valve base. The valve is the same in each case.

In addition, there are different styles of perforated ball mechanism itself:

A complete line of valves or better known has a large ball to the hole in the ball of the same size as the pipeline, which is at lower pressure. The flow is free, but the valve is larger and more expensive, so it is only used when free movement is necessary, as in pipes that require scraping.

In the reduced postage, or better known reduced bore ball valves through the valve is one pipe size smaller than the size of the pipe flow section of the valve that is smaller than the tube. As the output rate remains constant at the surface of the current (A) multiplied by the velocity (V) = A1V1 A2V2 increases the speed with low flow range.

AV valve ball port is available with a balloon in "V" or a "v" shaped seat. This opens the opening and closing a controlled manner with an almost linear characteristic. If the valve closed position and open the small end of the "v" was opened for the first time allows a stable flow control is initiated during this phase. This type of construction requires a more robust overall, attributable to higher rates of fluids as a standard valve may be damaged.
